Title: Microcomputer system
Inventor: SUZAKI SATORU
IPC: G06F15/02
Filed: 1984-01-13
Abstract: PURPOSE:To reduce the variations of the circuit state inside a microcomputer system consisting of a CMOS.IC and to reduce the power consumption, by reducing the speed of the clock which is given to a CPU while an idle routine is executed. CONSTITUTION:An address monitor circuit 5 decides the execution of an idle routine and delivers this execution mode to an AND gate 10 when the address which is presently executed by a CPU2 is within the upper and lower address ranges set by dip switches 8A and 8B. Thus an address bus 4 of the CPU2 is monitored by the circuit 5 and at the same time high-speed and low-speed clocks are produced from a clock generating circuit 6 according to the monitor result. In other words, a switch circuit 7 which switches the output of the circuit 6 is controlled by the output of the circuit 5. Then the speed of the clock supplied to the CPU2 is reduced while the CPU2 is executing a program of a low priority like a case where the CPU2 is executing an idle routine. This can reduce the variations of the circuit state as well as the power consumption.

IPC: G11B7/09
Filed: 1988-01-13
Abstract: PURPOSE:To prevent the generation of the reading errors of a jumping-up and the like even when a vibration is given to a pickup from a driving mechanism by increasing a track following capacity of the pickup with increasing the gain of a servo circuit at the time of a pickup moving. CONSTITUTION:When a motor driving circuit inputting voltage necessary to move the pickup exceeds a reference voltage, the output of a comparison circuit 7 inverts from an H level to an L level and turns off the switching transistors Q1 and Q2 of a focus and tracking gain changing circuits 8 and 9. Consequently, gain values R3 and R6 decided by resistors R1-R6 are increased by cutting off and the response of an objective lens to a focus error signal and a tracking error signal turns to be good. Thus, a reading point is kept on the track and the track can be followed well, even when the vibration generated at the time of an optical pickup 1 moving is given to the objective lens.

Filed: 1996-01-17
Abstract: PROBLEM TO BE SOLVED: To spin a yarn little in breakage of fibers constituting a fiber bundle to be drafted, having fibers arranged parallel in the longitudinal direction, homogeneous in yarn structure and excellent in strength. SOLUTION: A load cell c1 as a means for detecting the load 1 on a supporting shaft b1' of a top back roller b1 is placed at the front roller F-side of the supporting shaft b1'. An operator drives the back roller B in a state where a fiber bundle L does not pass, and monitors a display means 6 to determine a driving force (d) through the detection of the load cell c1. Subsequently, in the state where a fiber bundle passes, the operator monitors the display means 6 to determine the load 1 through the detection of the load cell c1. A draft resistance (r) in practice is determined from the difference between the load 1 and the driving force (d).  Thus, the operator monitors the load 1, detected in the state where a fiber bundle L is drafted, on the display means 6 and adjusts a draft ratio by changing the surface speed of the back roller so that the draft resistance (r) becomes an appropriate value.
